Glue Stop is a product used in volume and easy fan eyelash extensions to prevent lash adhesive from traveling up the fans. It keeps the lash fans blooming. 
How to use:
1. Apply a small amount of the glue stop to the extension lash strip, about 3-5mm away from the base.
2. Allie the glue stop to dry for a few seconds before applying the eyelash extension glue and attaching it to the natural lash.
3. Repeat the process every 6-8 hours to ensure the extensions remain open and do not close up.
